Cost-Effective Collaboration

Presence-AR is a secure, peer-to-peer technology that can add synchronous collaboration to almost any applicationfrom financial modeling to CADwithout requiring software modifications or data conversion. Presence-AR Adapter for PowerPoint 1.1 is a fine solution for distant teams that need to share and view presentations quickly, and it's a cost-effective alternative to complex collaboration programs.

Presence-AR lets Microsoft PowerPoint 2000/2002 users collaborate seamlessly in those familiar applications without having to learn a collaboration tool. Unlike screen-sharing solutions like WebEx, users can roam to slides other than the one the presenter is viewing.

After installing the 500K plug-in, you simply click the Begin Collaboration button added to PowerPoint's toolbar. This launches the Control Collaboration window, which shows which participants in your workgroup are available. It also lets you create a new collaboration session, join an existing one, display or hide your pointer, or jump into a public or whisper chat. To see other Presence-AR users, you must have the Directory Server component installed on your LAN.

When a host gives a presentation you don't already have, you can choose to download it all at once or progressively. Using the progressive download, the collaboration can start immediately; remaining slides get downloaded in the background. This lets all the participantseven those on slower connectionsmove along with the presentation.

For further optimization, wavelet compression and Gnutella-like distributed file-sharing protocols are used. If a presenter's connection gets lost, Presence-AR's unique mutability feature lets the presentation continue uninterrupted using another participant's PC as the presentation host.

Presence-AR works at the data layer and is device-, platform-, and application-independent, so users of Windows CE devices can collaborate on the same data. An Excel Adapter is also available, and a Microsoft Word Adapter is in the works.

Presence-AR Adapter for PowerPoint 1.1 is a novel collaboration solution that showcases the real promise of Presence-AR technology for applications.
